US Patent:

6566996, May 20, 2003

Filed:

Mar 29, 2000

Appl. No.:

09/537518

Inventors:

Robert Stephen Douglass - Wildwood MO
Matthew Rain Darr - Godfrey IL
Michael Craig Henricks - Ballwin MO

Assignee:

Cooper Technologies - Houston TX

International Classification:

H01H 8530

US Classification:

337243, 337244, 337206, 337265, 439488, 439489, 324550, 340638

Abstract:

A fuse state indicator includes a fuse casing having a transparent lens, a combustible substance disposed adjacent the lens, and a base layer disposed adjacent the combustible substance and having a contrasting color relative to the combustible substance. A secondary fuse indicating circuit is electrically connected to a main fuse circuit in parallel with a main fuse link, and includes a secondary fuse wire link which is disposed adjacent the combustible substance. Heat created upon vaporization of the secondary fuse link ignites the combustible substance and reveals the base layer through the lens after combustion, thereby indicating a state of the fuse as operable or inoperable by the color visible through the lens. Combustion may be assisted with an energetic chemical compound applied to secondary fuse wire link and combustible substance.

09/992852

Inventors:

Matthew Rain Darr - Alton IL
Robert Stephen Douglass - Wildwood MO

Assignee:

Cooper Technologies Company - Houston TX

International Classification:

H01H 8520

US Classification:

337187, 337189, 337255, 361833

Abstract:

A fuseholder includes a main housing configured for receiving a plurality of cartridge fuses, a fuse drawer configured for slidable insertion into the main housing, and a handle coupled to the drawer for opening the drawer to release fuses from the main housing. The drawer includes a retractable handle that is substantially flush with the drawer when the drawer is closed. A handle recess is located adjacent the drawer for prying the handle open with a tool. A drawer frame includes a lock opening therethrough for a lock member to prevent closing of the fuse drawer as desired. Built-in fuse rejection members are included in the main housing to prevent use of incorrect fuses with the fuseholder and an auxiliary contact actuator is provided for added features on an as needed basis.

US Classification:

340292, 340638, 340662

Abstract:

A circuit protector signal transmission system, kit and method involves at least one circuit protector defining an interruptible current path therethrough upon an occurrence of specified operating conditions in a circuit, a status element associated with the circuit protector and adapted to monitor an operating state of the current path, an electronic gateway device in communication with the status element and adapted to receive a data signal from the status element corresponding to the operating condition of the current path. The data signal includes location information and identification information for circuit protectors as they operate to interrupt the current paths in an electrical system.
